DETAILED DESCRIPTION

An apparatus that implement the embodiments of the various features of the present invention will now be described with reference to the drawings. The drawings and the associated descriptions are provided to illustrate embodiments of the present invention and not to limit the scope of the present invention. Reference in the specification to “one embodiment” or “an embodiment” is intended to indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least an embodiment of the present invention. The appearances of the phrase “in one embodiment” or “an embodiment” in various places in the specification are not necessarily all referring to the same embodiment. Throughout the drawings, reference numbers are re-used to indicate correspondence between referenced elements.

FIG. 1 is an exploded disassembled perspective view of a shoe chassis or shoe sole 2 according to an embodiment of the present invention. Shoe chassis 2 comprises a board 4, a flexible membrane 26, a cushioning material 24, a stabilizing unit 14, a first (i.e., front) pod 20, and a second (i.e., back) pod 18.

Board 4 has a first (i.e., front) end 6 and a second (i.e., back) end 8. Front end 6 can encompass an area proximate to a user's toes and back end 8 can encompass an area proximate to a user's heel. Board 4 may be made from a material such as paper, cardboard, wood, rubber, plastic, foam, leather, synthetic leather, or any combination of the above materials. Board 4 can also be constructed from any other firm, yet flexible material. Board 4 includes a first hole or opening 10 in or near second end 8 and a plurality of grooves 12 in or near first end 6. In one embodiment, plurality of grooves 12 are perforated. Plurality of grooves 12 allow board 4 to bend when shoe chassis 2 is bent in response to a movement from a user's foot. This allows for greater comfort for the user's foot and also allows the user better control of movement of shoe chassis 2.

The shape of first hole 10 is defined by the cutout in board 4. In one embodiment, first hole 10 is shaped and sized to be similar to the shape and size of a user's heel. The cutout allows the user's heel to fit within first hole 10 for better comfort and support. In FIG. 1, first hole 10 has a front side with a flat edge and a back side with a semi-circular edge. First hole 10 can be formed in the shape of a circle, an oval, a semi-circle, a square, a triangle, an ellipse, or any combination of the above shapes.

Flexible membrane 26 can cover or be positioned within first hole 10. Flexible membrane 26 allows the heel to flex past or through first hole 10 and compress cushioning material 24, which is under flexible membrane 26. As shown in FIG. 1, flexible membrane 26 is die cut and zig zag stitched to board 4. Flexible membrane 26 can also be attached to board 4 through a variety of means including, but not limited to, other types of stitching, adhesives, and/or fasteners.

In one embodiment, flexible membrane 26 is a soft, stretchable and durable cushion material or membrane such as ethylene vinyl acetate (EVA), foam, plastic, and/or rubber. Flexible membrane 26 can also be formed from any other type of flexible material. In one embodiment, flexible membrane 26 has relatively the same thickness as board 4. It is also contemplated, however, that flexible membrane 26 can be thinner or thicker than board 4.

Stabilizing unit 14 is located beneath board 4 and includes a second hole 16 located directly beneath first hole 10 of board 4. Board 4 fits within stabilizing unit 14. Stabilizing unit 14 is constructed of thermoplastic polyurethane that is injection molded. Stabilizing unit 14 can also be constructed of any other type of material that is semi-flexible such as rubber, plastic, foam, etc. Stabilizing unit 14 can be used to stabilize the heel and shank of the user. If flexible membrane 26 is thicker than board 4, it may extend into second hole 16.

Second hole 16 has a front side with a flat edge and a back side with a semi-circular edge. Second hole 16 can be formed in the shape of a circle, an oval, a semi-circle, a square, a triangle, an ellipse, or any combination of the above shapes. Second hole 16 can also have the same shape or a different shape as first hole 10.

First pod 20 and second pod 18 are located below stabilizing unit 14 to provide support for stabilizing unit 14 and board 4. First pod 20 and second pod 18 can be connected together using an arch or bridge (not shown) made of a plastic, rubber or other material. Second pod 18 includes a cutout or depression 22 located directly beneath second hole 16. First pod 20 and second pod 18 are high abrasion rubber forefoot and heel pods, respectively. First pod 20 and second pod 18 can be constructed from flexible, yet extremely durable materials such as other types of rubber, plastic, etc.

Cushioning material 24 is located within depression 22. In one embodiment, cushioning material 24 is a soft and durable cushioning material such as ethylene vinyl acetate (EVA), gel, foam, plastic, and/or rubber. Cushioning material 24 can be formed from any other type of cushioning material. In one embodiment, cushioning material 24 can fill depression 22 such that it has the same height as second pod 18. Cushioning material 24 can protrude upward from depression 22 and partially or completely fill second hole 16.

In operation, a user places a heel of his foot onto flexible membrane 26. The heel contacts and stretches or bends flexible membrane 26 and puts pressure on flexible membrane 26. The pressure is translated from flexible membrane 26 through second hole 16 and onto cushioning material 24.

Since the force is translated from flexible membrane 26 through second hole 16 and onto cushioning material 24, there is a greater cushioning effect. That is, the force from the heel will generally be absorbed by flexible membrane 26 and then absorbed by cushioning material 24 instead of being absorbed by board 4 and/or stabilizing unit 14. This is advantageous since flexible membrane 26 and cushioning material 24 provide better cushioning than board 4 and/or stabilizing unit 14.

Furthermore, by having two holes 10 and 16, that is first hole 10, which is covered by only flexible membrane 26, and second hole 16, the user's heel has relatively direct access to cushioning material 24. Such a configuration may prevent the user's heel from sliding around board 4 and may allow the user to have better control of shoe chassis 2. This allows the user to move at a faster pace with greater comfort. This can also be beneficial when a user is using shoe chassis 2 for strenuous activities such as walking rapidly, jogging, and/or running.

FIG. 2 illustrates a shoe chassis 200 including an outsole 205, a first cushioning member 255, a second cushioning member 260 and a footbed 265. The shoe chassis 200 may be a portion of a shoe. As shown, outsole 205 may include a top surface 215 defining the upper bounds of a first cavity 220 and a second cavity 235, respectively. The top surface 215 may also define an arch support region of the outsole positioned between the first cavity 220 and the second cavity 235. As configured, the first cavity 220 may be located beneath or proximal to a user's forefoot (or the balls of the user's foot), while the second cavity 235 may be located beneath or proximal to a user's heel when the shoe chassis 200 is supporting a user's foot. The first cavity 220 may be defined by a first side wall 225 and a first bottom surface 230. The second cavity 235 may be defined by a second side wall 245 and a second bottom surface 250. As shown the first bottom surface 230 and the second bottom surface 250 may be positioned between the top surface 215 and a bottom surface for contacting a ground. The outsole 205 may further include an outer lip 210 attached to the circumference of the top surface 215. The outer lip 210 and the top surface 215 may define a third cavity for receiving the footbed 265 and/or any additional intervening layers (not shown). The outsole 205 may be constructed or molded out of any appropriate material such as rubber, plastic and the like. As shown, the outsole 205 may be configured to contact a ground surface and may keep the user's foot, protected, raised and/or supported.

The first cavity 220 and the second cavity 235 of the outsole 205 may be designed to receive and secure the first cushion member 255 and the second cushion member 260, respectively. The first cushioning member 255 may be sized and shaped to be substantially similar to the size and shape of the first cavity 220, thereby filling the first cavity 220 when positioned within the first side walls 225. In this manner, a top surface of the first cushioning member 255 may be planar with the top surface 215. Alternatively, the first cushioning member 255 may be designed to protrude out of the first cavity 220, or may be designed to have a smaller depth than a depth of the first cavity 220. Having a smaller depth may be beneficial where a thin layer of material may also be desired to fit within the first cavity 220 to provide cushioning or other functions. In an analogous manner, the second cushioning member 260 may be placed and secured within the second cavity 235. Furthermore, any attribute described with respect to the first cushioning member 255 may be provided to the second cushioning member 260.

The footbed 265 may be placed on top of the outsole 205, substantially covering the top surface 215, the first cushioning member 255 and the second cushioning member 260, thereby completing the shown portion of the shoe chassis 200.

The shoe chassis 200 may be considered a dual-cushioned shoe chassis as it includes two distinct cushioning members 255 and 260. In one embodiment, the outsole 205 may further define another cavity positioned between the first cavity 220 and the second cavity 235 for receiving a third cushioning member (not shown). In such an embodiment, the third cushioning member may be constructed out of the same or different material in order to provide support for the arch of the user's foot.

FIG. 3 illustrates another embodiment of a shoe chassis 300 including an outsole 305, a cushioning member 340 and a footbed 345. The outsole 305 may include a welting layer 310. The welting layer 310 may be constructed out of leather, suede or any other durable material, and may substantially span the entirety of the upper surface of the outsole 305. The welting layer 310 may also define an upper boundary of a cavity 330. As shown, the cavity 330 may be defined by a side wall 320 and a bottom surface 325. The cavity 330 may be positioned within the outsole 305, above a heel 315 of the outsole 305 without extending to a shank 335 of the outsole 305. The outsole 305 may be constructed out of one or more materials, including but not limited to rubber, plastic, cork, leather, and any combination or derivatives thereof (e.g., synthetic rubber, plastic, leatherette, etc.).

The heel 315 of the outsole 305 may be designed to be between 0.25 to 1.5 inches thick and may raise the overall profile of the shoe chassis 300. The heel 315 may be attached to the shank 335. The shank 335 may be substantially thinner than the heel 330, and may be 0.05 to 1.0 inches thick, and may be configured to support the arch and forefoot of the user's foot. As shown, the outsole 305 may be configured to contact a ground surface and may keep the user's foot, protected, raised and/or supported.

The cavity 330 of the outsole 305 may be designed to receive and secure the cushioning member 340. The cushioning member 340 may be sized and shaped to be substantially similar to the size and shape of the cavity 330, thereby filling the cavity 330 when positioned within the side walls 320. In this manner, a top surface of the cushioning member 340 may be planar with the top surface of the welting layer 310. Alternatively, the cushioning member 340 may be designed to protrude out of the cavity 330, or may be designed to have a smaller depth than a depth of the cavity 330. Having a smaller depth may be beneficial where a thin layer of material may also be desired to fit within the cavity 330 to provide cushioning or other functions.

As shown, the footbed 345 may be placed, and/or positioned, on the welting layer 310 and cover the cushioning member 340. The footbed 345 may be designed to contact a user's foot to provide additional cushioning and/or support.

As shown, the outsole 405 may include a forefoot portion 410 attached to a heel portion 440. The area directly proximal to the point of attachment may be for supporting an arch of a user's foot. The forefoot portion 410 may include a toe lip 415 which may extend upward (appearing in this embodiment as wings) about a portion of the perimeter of the outsole 405. The toe lip 415 may further extend into a portion of the heel portion 440. The heel portion 440 may include a heel 420 comprising three layers: an outer layer 425, a midsole 430 and an upper layer 435. The outer layer 425 may be constructed out of rubber or other suitable material for contacting a ground. The outer layer 425 may be attached to the midsole layer 430, which may be constructed out of EVA. The midsole layer 430 might not have a uniform thickness and may be thicker on a heel end and taper to a thinner thickness as it approaches the forefoot portion 410. In this manner, when the upper layer 435 is positioned on top of the midsole layer 430, it may provide a slanted or tapered supporting surface even if the upper layer 435 has a uniform thickness. As shown, the upper layer 435 may include the top surface of the heel portion 440 defining an upper boundary of a cavity 450, a side wall 445 defining a side boundary of the cavity 450 and a bottom surface 455 defining a bottom boundary of the cavity 450.

In one embodiment, the bottom surface 455 may be the top surface of the midsole layer 430. In this embodiment, the upper layer 435 may be considered to include an aperture for the receiving of the cushioning member 460.

The cushioning member 460 may be received and housed by the cavity 450. The cavity 450 of the outsole 405 may be designed to receive and secure the cushioning member 460. The cushioning member 460 may be sized and shaped to be substantially similar to the size and shape of the cavity 450, thereby filling the cavity 450 when positioned within the side walls 445. In this manner, a top surface of the cushioning member 460 may be planar with the top surface of the heel portion 440. Alternatively, the cushioning member 460 may be designed to protrude out of the cavity 450, or may be designed to have a smaller depth than a depth of the cavity 450. Having a smaller depth may be beneficial where a thin layer of material may also be desired to fit within the cavity 450 to provide cushioning or other functions.

The footbed 465 may be designed to cover the heel portion 440 and the forefoot portion 410, including the cushioning member 460. In this manner, the footbed 465 may be designed to contact a user's foot to provide additional cushioning and/or support.

While shown to be two distinct portions in FIG. 4, in one embodiment, the outsole 405 may include an integrated bed for supporting the forefoot, the arch and the heel of the user's foot.
